So far, there have only been few studies concerning the question of indication and efficacy of antidepressive medication in children and adolescents with anorexia nervosa and depressive episode in the course of an inpatient treatment. In addition, there is a lack of studies comparing the tolerability and efficacy of different antidepressants given to anorectic patients of this particular age group. This study compares paroxetine, a specific SRI, with clomipramine, a TCA with SRI activity, concerning the frequency and quality of adverse side effects, the frequency and the reasons for discontinuating the antidepressive treatment and different outcome measurements.83 female patients, aged 10.9 to 18.1 years, who underwent an inpatient treatment at the Departement of Child and Adolescent Psychiatry and Psychotherapy at the University of Wuerzburg, Germany, were enrolled in this retrospective study. All of them met the ICD-10 criteria for anorexia nervosa and depressive episode and received an antidepressant medication with clomipramine or paroxetine. We collected data from basic documentation, treatment reports, and the multiaxial classification (MAS). Outcome measurements were the duration of treatment (days) and the increase of body weight (kg/m2).The discontinuation of the antidepressive treatment due to adverse side effects or a lack of efficacy was significantly more frequent with clomipramine than paroxetine (33.3 vs. 15.4%). The increase of body weight (2.8 vs. 2.6 kg/m2) was similar in both groups, but the duration of treatment was significantly shorter under paroxetine (71.9 vs. 96.5 days).A shorter duration of treatment, faster increase of body weight, lower percentage of dicontinuating the antidepressive medication and last but not least economic reasons lead to the conclusion, that paroxetine should be preferred in female adolescents with anorexia nervosa and depressive episode. However, prospective studies are needed to confirm our findings.
